High energy-density battery cells

Double the charge for next‑gen anode-free batteries

HeiQ GrapheneX is a new anode-free class of high energy-density battery cells designed for demanding applications where weight, runtime, and power matter. The cells enable higher energy output within the same footprint, supporting longer operation times or reduced battery weight. They are developed for use in real devices and scalable industrial production.

    HeiQ GrapheneX is used inside lithium batteries to increase energy density. Performance characterization shows up to double energy density at battery cell level. The technology supports drop-in lithium‑metal and anode‑free cell designs without changing established lithium ion production lines.

    Conventional approaches rely on bulk material changes. HeiQ GrapheneX uses a thin graphene membrane that controls lithium behavior at the interface level. This enables lithium‑metal and anode‑free cell designs without the use of flammable graphite.

    HeiQ GrapheneX is designed for industrial relevance. It has been validated at cell, battery and device level and is compatible with existing lithium ion battery manufacturing processes.
